What is the doom painting?

A 'Doom' is the traditional English term for a painting or image that reflects The Bible's depiction of the 'Last Judgement.' It refers to the judgement of souls and whether they're sent to Heaven or hell. These paintings are common on the Western walls of numerous churches in England. The most famous Doom painting is the Last Judgement by Michelangelo, which is in the Sistine Chapel, the residence of the Pope in Vatican City, Italy.
